Android Headunit no 4g

[Mike_G]

Evening 

recently added a second line for my Android car headunit. 

Tested previously with a lebera SIM card which connected nonissue on 4g

Once the new ee sim was activated and installed. It failed to connect. After some playing about I have managed to get it to connect on GSM with 3G but can’t get LTE to work. 

no matter what I set it to (automatic or fixed to a setting) I can’t get a 4G connection. I do get a 4G connection on my iPhone 14 pro (sitting about 30cm away) 

I remember I had a GPS tracker a while ago that needed a 3G only sim. But as the lebera card worked I know the unit supports 4G

any ideas would be appreciated 

thanks

If you put your phone SIM into your car unit, does it get a 4G connection?

Same question for the car SIM into your phone?

What's the make & model of your car unit?

No my iPhone has an esim. 

using the new sim in my iPhone gives me 4G

the unit is a road top 10.2 running Android 11. It’s a replacement screen for the Mercedes.

@Mike_G   If the sim gives you 4G on your phone then the issue lies with the unit itself.    Have you put EEs APN setting in to the unit ?

Well low and behold. Came out this morning to scrape the car. Fired up the headunit and boom. Got a 4g connection. 

I moved it from the gsm o my setting to gsm/lte. And it’s stuck at 4g. 

not sure what it was up I last night. Maybe the snow starting was affecting the communications 😂
